New Horizons Io Observations

Below is a collection of Io images acquired by the New Horizons spacecraft as it flew by Jupiter and Io in late February and Early March 2007. For each observation, I have converted the original PDS LORRI images to 16-bit PNG images using the ESA/ESO/NASA FITS Liberator plugin for Photoshop. Those are the images linked next to "Original Image". I then rotated those images so north was up (linked next to "Rotated Image"). Next, I sharpened the rotated images using Photoshop's Unsharp Mask tool (settings used - Amount: 293%; Radius: 0.9 pixels; Threshold: 0 levels). These images are linked next to "Rotated/Sharpened Image". Finally, I cropped around Io (linked from the preview image in the left column and next to "Cropped Image") and magnified by 200% ("Magnified Image"). For many observations, I also linked to images I processed last year, including versions where I combined the LORRI data with color data from Galileo ("Colorized Image") or where I labeled various features visible in the LORRI image ("Annotated Image"). I also put together color images from any MVIC data taken during the observation.

The Celestia preview images show the surface of Io visible from New Horizons during each observation (with versions with or without a latitude and longitude grid).
